BUFFING- OR POLISHING WHEEL.

Specication of Letters Patent.

Patented Apr. 5, 1921.

Application filed. April 16. 1919. Serial No. 290,449.

To all/whom 'it may concern.'

Be it known that I, ALEXANDER LEvE'r'r, a citizen of the United States, anda resldent of the city of New York, borough of Manhattan, in the county and State of New York, have inventedv a new and Improved Buiiing .or Polishing Wheel, of which the following is a full, clear, and exact description. 1

The object of the invention is to provide a new and improved buing or polishing wheel arranged to combine with the body of the wheel a polishing compound to insure the formation of a high quality of polish on the article to bepolished and without requ1r-' ing the Workman to periodically apply a polishing compound to the perlpheral face of the wheel as now generally practised. Another object is to render the polishing wheel'when in use very effective leaving the' Y work exceedingly bright and clean without any particles of the polishing compound being lodged in or adhering to the interstices, crevices or the like, or the filigree work or other ornamentations on the article to be polished or. bui'ed at the time. Another object is to prevent the liber disks formin thel body ofthe polishing or buffing wheel rom unraveling. Another object is to allow the disks to expand or stretch in every direction thus providing the desired elasticity in the body of the wheel and insuringl a proper polishing or buling action along the entire peripheral face of the bufiing or polishing wheel.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shownv and described vand then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 isla cross section of the buing or polishing wheel, the section being on the line 1-1 of Fig. 2;

Fig; 2 is a face view of the samegwith a portion of one of the facing disks broken out;

Fig. 3 is an enlarged face View of the central portion of one of the disks; and

Fig. 4 is an enlarged sectional plan view of one of the disks, line of Fig. 2.

cent the central opening 13 and of the section being on the The bodylO of the polishing or bulingV wheel is formed of a series of layers 11 of cloth or other suitable fibrous material, the layers being fastened together by stitches 12, and -the layers are provided with 'registering central passage of the shaft carrying the bufling or polishing wheel. Each of and impregnated with a polishing compound 14 formed of tripoli, emery or other suitable polishing powder, and a mucilaginous non-greasy paste, the compound filling the meshes of the layers and adhering to the faces thereof thus somewhat stiffening the layers. is formed of Houror water to which the emery or tripoli is added in about the proportions (dry measure) of one-half pint of paste to one pint of tripoli. In practice, each of the layers 11 ispreferably provided with perforations or punctures 15 distributed promiscuously and lled 'with the polisching compound thus increasing the edi-1 `c1ency or polishing quality ofthe wheel. It is understood that the polishing compoundl owing to its mjucilaginous nature firmly holdsl the threads of the layer together thus preventing unraveling` of the threads at the peripheral face of the wheel.

Vhen uslng a woven textile .material for the layers 11, each layer is preferably provided with slits 16 and 17 arranged adiaslits 16 are disposed approximately parallel to the weft 'while the slits 17 are disposed approximately parallell to the warp oi the woven textile material, as will be readily understood by reference to Fig. 3. understood that the'cloth or similar woven textile fabric ,stretchesv diagonally but not in the direction of the warp or the weft, but by providing the slits layer is capable of stretching in every direction thus providing the desired elasticity in each layer to insure a proper polishing action along the entire peripheral face of the bufling or polishing wheel. "Wheny malng the body 10 of superimposedsmall `scraps of cloth then the slits 16 and 17 'need not be necessarily at right an les to the weft and warp.

The polishing compound as above `described, is of a greaseless nature and is incorporated with the body, each layer being independently and separately treated. Glue is not used, as the glue form a gummy the layers 11 is coatedwhich the The polishing compound or paste It is 16 and 17 Vthe matter and will gum and stick into the interstices of the work and would be objectionable as oil or oily matter. The wheel is pliable and the polishing compound being stitched in between the rows of spiral stitches more than in being soaked -in the layer being independently treated, coated or impregnated and then the layers being stitched with narrow rows of spiral stitches. The compound for polishing is thereby incorporated into the body and being of a Agreaseless nature, will not adhere or gum up, as will glue or oil, when they latter is soaked into the cloth and is somewhat heavy and sticky.

lHaving thus described my invention, I claim as new and desire tosecure by Letters Patent l. A polishing or -bufiing wheel having a body formed of superimposed layers of woven textile fabric, each layer being provided with a central opening and with slits adjacent the central opening, sundry of the slits extending approximately parallel to the weft and sundry of the slits extending approximately parallel to the warp.

2. A polishing or buiiing. wheel having a body formed of superimposed layers of woven textile fabric, each layer being provided with a central opening and with slits adjacent the central opening, sundry of the slits extending approximately parallel to the weft .and sundry of the slits extending approximately parallel to the warp, and a greaseless polishing compound adhering to and stilfening the said layers.

3. A polishing or bufiing wheel having a body formed of superimposed layers of fibrous material, each layer being provided with perforations, and an abrasive greaseless filler filling the meshes and perforations of the layers and adhering to the faces thereof.

4. A polishing or buliing wheel having a body formed of superimposed layers of fibrous material, each .layer being provided with perforations, and a filler filling the meshes and perforations 0f the layers andadhering to the faces thereof, the said filler being formed of a polishing powder and a mucilaginous substance of a greaseless nature with which said layers are impregnated and coated.

5. A polishing or bufling wheel having f i a` body formed of superimposed layers of woven textile fabric, each layer being pro-l vided with a central opening and with slits adjacent the central opening, sundry of thel slits extending approximately parallel tothe weft and sundry of the slits extending approximately parallel to the warp, alternate layers having their slits out of register.
